Sensitivity and specificity of vCGH, rGEP and sGEP compared with CGH on 64 MCLs. (A) Gain. (B) Loss. Each subfigure represents one chromosome. Sensitivity and specificity was shown on X and Y axis, respectively. Different prediction methods were shown in colors-- rGEP in light green, sGEP in dark green, vCGH Viterbi in red, and vCGH Posterior in a series of colors representing different posterior probability cut-offs (p = 0.5, 0.6, 0.7, 0.8 and 0.9).
